Can Excel actually find the roots to high precision without numerical problems? I had the impression that Excel was a disaster waiting to happen for this sort of thing, just due to horrible numerics implementation.

It wasn't able to find the roots to high precision, but thankfully it was accurate enough for my purposes.
